Download and read online ebook Zooplankton Ecology write by Maria Alexandra Teodosio. This book was released on 2020-11-19. Zooplankton Ecology available in PDF, EPUB and Kindle. This book aims at providing students and researchers an advanced integrative overview on zooplankton ecology, covering marine and freshwater organisms, from microscopic phagotrophic protists, to macro-jellyfishes and active fish larvae. The first book section addresses zooplanktonic organisms and processes, the second section is devoted to zooplankton spatial and temporal distribution patterns and trophic dynamics, and the final section is dedicated to emergent methodological approaches (e.g., omics). Book chapters include comprehensive synthesis, observational and manipulative studies, and sediment-based analysis, a vibrant imprint of benthic-pelagic coupling and ecosystem connectivity. Most chapters also address the impacts of anticipated environmental changes (e.g., warming, acidification).

Whatever theory may be advanced to explain diurnal migration, the underlying reactions involved must be demonstrated conc- sively in the laboratory before the explanation can be ?nally accepted George L. Clarke 1933 p. 434 In oceans and lakes, zooplankton often make diel vertical migrations (DVM), descending at dawn and coming up again in late afternoon and evening. The small animals cover distances of 10–40 m in lakes or even a few hundred metres in the open oceans. Although not as spectacular as migrations of birds or the massive movements of large mammals over the African savannas, the numbers involved are very large and the biomass exceed the bulk of the African herds. For example, in the Antarctic oceans swarms of “Krill” may cover kilometres across, with thousands of individuals per cubic metre. These Euphausiids are food for whales, the most bulky animals on earth. Zooplankton are key species in the pelagic food web, intermediary between algae and ?sh, and thus essential for the functioning of the pelagic community. Prey for many, they have evolved diverse strategies of survival and DVM is the most imp- tant one. Most ?sh are visually hunting predators and need a high light intensity to detect the often transparent animals. By moving down, the well-lit surface layers are avoided but they have to come up again at night to feed on algae.

The need for a volume dealing with the concept of indicator organisms became evident during a symposium on the subject, organized by the present editors for the Southern California Academy of Sciences. Ques tions were posed about the appropriate uses of indicator organisms and the "rules" governing the application of the indicator concept to particular problems. For example, how does one distinguish true indicators from biological anomalies? What kinds of organisms can appropriately be associated with conditions and events at various scales in time and space? To what extent does one species represent other species in the same environmental setting? Can the indicator concept be applied to the context of modern sampling and analytical technology? How can anthropogenic perturbations be distinguished from natural phenomena? How can unlike matrices from differing data bases with differing scales best be matched? Such questions are especially pertinent in today's research environment. The use of indicator organisms, while certainly not new, is the corner stone for much scientific research. In the past two decades, indicator organisms have played increasingly important roles in the development and implementation of public policy. In particular, indicator organisms are being used to describe local environments and natural or anthropogenic perturbations to them, although there are pitfalls and problems associated with those usages. A growing number of nonbiologists, including physical oceanographers, find indicator organisms helpful, and sometimes essential, to their re search.
